[SOLVED] System not booting into UEFI

I'm having some issues getting my system to boot into UEFI mode. I discovered this as I was attempting to get fwupd up and running, but it kept complaining about capsule updates not available/enabled, and that the firmware cannot be updatedin in legacy BIOS mode.

Realizing that /sys/firmware/efi didn't exist, I set about to get UEFI enabled. I booted into the admincd (admincd-amd64-20210630T214504Z.iso), mounted my hard drives, did the bind mounts, and ended up in a chroot with /sys/firmware/efi being populated. So I ran grub-install --efi-directory=/boot/ (/boot/ is my fat32 EFI partition, and it does have the esp flag), followed by grub-mkconfig -o /boot/grub/grub.cfg. At that time, it did mention installing the UEFI menu item.

However, after a reboot back into the normal system, I'm still not seeing /sys/firmware/efi existing, and efibootmgr -v reports "EFI variables are not supported on this system."

Is there something else I need to do in order to enable UEFI boot on my system?

Is your BIOS set to boot via UEFI?

Yes, it is set for UEFI, and when I pull up a boot menu, it lists it as UEFI.

I was thinking about this right after I posted my reply, I realized that as part of digging around on what the possible culprits would be that I hadn't checked my kernel config. A quick grep for EFI in /usr/src/linux/.config confirmed my fears. CONFIG_EFI_PARTITION was set to yes, but CONFIG_EFI was not set. Set it to y, rebuilt, and now I'm seeing /sys/firmware/efi, and fwupdmgr is able to see my BIOS info. Thanks for helping me think through it.
